P0244 Turbocharger wastegate solenoid "A" signal is out of range

P0244 – OBD-II Trouble Code Technical Description

Trouble code P0244 indicates that the turbocharger wastegate solenoid "A" signal level is out of range.

What does the fault code mean P0244?

Trouble code P0244 indicates a malfunction in the turbocharger wastegate solenoid “A” circuit. This means that the engine management system (ECM) has detected an anomaly in the operation of solenoid “A”, which regulates the turbocharger boost pressure.

Fault code P0244.

Possible reasons

Several possible reasons for the P0244 trouble code:

  • Faulty bypass valve solenoid: The solenoid itself may be faulty due to wear, corrosion or other reasons, resulting in improper operation.
  • Solenoid wiring or electrical connections: Breaks, corrosion, or poor connections in wiring, including connectors or wiring harness, can cause problems with signal transmission to the solenoid.
  • Problems with the engine control module (ECM): Malfunctions in the engine control module itself can cause the solenoid to malfunction, resulting in a P0244 code.
  • Improper installation or adjustment of solenoid: If the solenoid has recently been replaced or adjusted, improper installation or adjustment may cause it to not operate properly.
  • Boost pressure problems: High or low boost pressure in the turbocharger system can also cause trouble code P0244 to appear.
  • Mechanical problems with turbocharger: Incorrect operation of the turbocharger, for example due to wear or damage, can also cause the P0244 code.

To accurately determine the cause of the problem, it is recommended to conduct a thorough diagnosis under the guidance of a qualified technician.

What are the symptoms of a fault code? P0244?

Symptoms when trouble code P0244 is present may include the following:

  • Loss of power: One of the most common symptoms is loss of engine power due to improper operation of the turbocharger wastegate solenoid.
  • Difficulty accelerating: If the solenoid is not working properly, the turbocharger may have difficulty accelerating, especially when trying to provide additional power.
  • Changes in engine performance: Changes in engine performance may be noticed, such as rough idling, vibrations, or rough running.
  • Check Engine Light Appears: The activation of the Check Engine light on your dashboard may be the first sign of a problem.
  • Increased fuel consumption: Improper operation of the wastegate solenoid can result in increased fuel consumption due to inefficient operation of the turbocharger.
  • Unusual sounds or vibrations: In some cases, unusual sounds from the turbocharger or engine may be noticed, as well as vibration in the engine area.

These symptoms may occur to varying degrees depending on the specific problem and the characteristics of the vehicle. If you notice one or more of these symptoms, it is recommended that you contact a certified auto mechanic to diagnose and repair the problem.

How to diagnose a fault code P0244?

To diagnose DTC P0244, the following steps are recommended:

  1. Reading the error code: Using the OBD-II diagnostic scanner, read the P0244 error code and any other error codes that may be related to the problem.
  2. Visual inspection of the solenoid and its surroundings: Check the turbocharger wastegate solenoid for visible damage, corrosion or leaks. Also carefully inspect the electrical connections and wiring for damage.
  3. Checking electrical connections: Check the solenoid electrical connections for oxidation, damaged or broken wires.
  4. Measuring Solenoid Resistance: Using a multimeter, measure the resistance of the solenoid. Resistance must be within manufacturer specifications.
  5. Checking the supply voltage: Check the supply voltage to the solenoid while the engine is running. The voltage must be stable and within the manufacturer's specifications.
  6. Checking the control signal: Check if the solenoid receives control signal from the ECM while the engine is running.
  7. ECM diagnostics: If necessary, perform additional diagnostics on the ECM to check its functionality and the correct solenoid control signal.
  8. Checking boost pressure: Check the turbocharger boost pressure, as pressure problems can also cause P0244.

Diagnostic errors

When diagnosing DTC P0244, the following errors may occur:

  • Insufficient solenoid diagnostics: The turbocharger wastegate solenoid itself is not sufficiently diagnosed, which may result in the problem being missed or misdiagnosed.
  • Incorrect resistance or voltage measurement: Incorrect measurement of solenoid resistance or voltage may lead to incorrect conclusions about its condition.
  • Skipping a visual inspection: A mechanic may skip a visual inspection of the solenoid and its surroundings, which may result in missing obvious problems such as damage or leaks.
  • Incorrect ECM diagnosis: Incorrect diagnosis or insufficient testing of the Engine Control Module (ECM) may lead to incorrect conclusions about the cause of the error.
  • Incorrect interpretation of scanner data: Incorrect interpretation of data received from the OBD-II scanner may lead to incorrect diagnosis and repair.
  • Incorrect component replacement: Replacing the solenoid without prior diagnosis or based on incorrect findings may be unnecessary if the problem lies elsewhere.

To avoid these errors, it is important to carry out a thorough and systematic diagnosis under the guidance of a qualified technician and use the correct equipment.

How serious is the fault code? P0244?

Trouble code P0244 can be serious depending on the specific circumstances and reasons for its occurrence. Several factors that can determine the severity of this problem:

  • Level of damage or defect: If the cause of the P0244 code is a severely damaged or broken turbocharger wastegate solenoid, it can cause serious problems with engine performance and turbocharging system efficiency.
  • Potential effects on the engine: Improper operation of the wastegate solenoid can cause uneven air flow to the engine, which in turn can lead to loss of power, increased fuel consumption and even engine damage.
  • Possibility of other problems: Trouble code P0244 can also be an indicator of other problems in the turbocharging system or engine management system. Failures in these systems can have more serious consequences for the vehicle's performance.
  • Potential Economic Impact: Repairing or replacing the turbocharger wastegate solenoid can be costly. In addition, improper operation of the turbocharging system can lead to increased fuel consumption, which will also affect the owner’s finances.

Overall, although the P0244 code is not an emergency, it can cause serious problems with your vehicle's performance and requires careful attention and timely repair.

What repair will help eliminate the code? P0244?

Depending on the diagnostic results, the following repairs may be required to resolve DTC P0244:

  1. Bypass Valve Solenoid Replacement: If the solenoid is found to be faulty or damaged, it must be replaced with a new one.
  2. Repair or replacement of electrical wiring: If breaks, corrosion or poor connections are found in the wiring, the affected sections of the wiring must be repaired or replaced.
  3. Check and, if necessary, replace the ECM: In some cases, the problem may be due to a problem with the Engine Control Module (ECM) itself, and replacement may be necessary.
  4. Checking and cleaning the intake system: Sometimes solenoid problems can be caused by a clogged or damaged intake system. Check for problems and make any necessary cleaning or repairs.
  5. Checking the vacuum system: If the vehicle uses a vacuum turbo control system, the vacuum lines and mechanisms should also be checked for leaks or defects.
  6. Checking the on-board electrical system: Check the vehicle electrical system for short circuits or wiring problems that could cause P0244.

Repairs should be performed by a qualified mechanic using the correct equipment and after thoroughly diagnosing the problem.

    Dear Sir!
    Re:P0244
    This error appeared in my car yesterday, while traveling on the highway. For the first time, an error message appeared and was accompanied by a decrease in performance. It went away after a few seconds.
    During the journey, the error signal appeared several times and went off by itself. I just read out with OBD what the cause is.
    My question is, is it possible that the error is caused by a soot deposit that prevents the movement of the valve, which can perhaps be eliminated with an engine cleaner-de-soot additive?
